What this MCCB brings to the panel
The Siemens SENTRON 3VA2216-8JP32-0AA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed as the cabinet heats up. Its interrupting capacity hits 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 53 kA at 690 V — numbers that put it squarely in high-fault-duty territory for industrial mains or large sub-distribution. The ETU550 electronic trip unit gives you adjustable long-time delay (tr from 0.5 to 25 s) and short-time delay (tsd up to 0.5 s), so you can shape the curve for selective coordination downstream. Rated insulation voltage is 800 V, and the front face carries IP40 protection — fine for a clean indoor panel, but not for washdown zones. Communication function is built in, which means it can talk to a higher-level system for metering or remote trip indication — useful if you're integrating into a BMS or SCADA layer.
Footprint and panel fit
Dimensions are 86 mm deep, 105 mm wide, and 181 mm tall — a standard SENTRON 3VA frame size that drops into existing 3VA panel cutouts without modification. Mechanical endurance is rated at 20,000 operations. Maximum power loss is 19.7 W, so factor that into your enclosure thermal budget if you're packing several breakers side by side.
